7710CS–AVR–01/08
The AVR core combines a rich instruction set with 32 general purpose working registers. All the
32 registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two independent
registers to be accessed in one single instruction executed in one clock cycle. The resulting
architecture is more code efficient while achieving throughputs up to ten times faster than conventional CISC microcontrollers.
The AT90PWM216/316 provides the following features: 16K bytes of In-System Programmable
Flash with Read-While-Write capabilities, 512 bytes EEPROM, 1024 bytes SRAM, 53 general
purpose I/O lines, 32 general purpose working registers,three Power Stage Controllers, two flexible Timer/Counters with compare modes and PWM, one USART with DALI mode, an 11channel 10-bit ADC with two differential input stage with programmable gain, a 10-bit DAC, a
programmable Watchdog Timer with Internal Oscillator, an SPI serial port, an On-chip Debug
system and four software selectable power saving modes.

AT90PWM216/316
The Idle mode stops the CPU while allowing the SRAM, Timer/Counters, SPI ports and interrupt
system to continue functioning. The Power-down mode saves the register contents but freezes
the Oscillator, disabling all other chip functions until the next interrupt or Hardware Reset. The
ADC Noise Reduction mode stops the CPU and all I/O modules except ADC, to minimize switching noise during ADC conversions. In Standby mode, the Crystal/Resonator Oscillator is running
while the rest of the device is sleeping. This allows very fast start-up combined with low power
consumption.
The device is manufactured using Atmel’s high-density nonvolatile memory technology. The Onchip ISP Flash allows the program memory to be reprogrammed in-system through an SPI serial
interface, by a conventional nonvolatile memory programmer, or by an On-chip Boot program
running on the AVR core. The boot program can use any interface to download the application
program in the application Flash memory. Software in the Boot Flash section will continue to run
while the Application Flash section is updated, providing true Read-While-Write operation. By
combining an 8-bit RISC CPU with In-System Self-Programmable Flash on a monolithic chip,
the Atmel AT90PWM216/316 is a powerful microcontroller that provides a highly flexible and
cost effective solution to many embedded control applications.
The AT90PWM216/316 AVR is supported with a full suite of program and system development
tools including: C compilers, macro assemblers, program debugger/simulators, in-circuit emulators, and evaluation kits.
4.2 Pin Descriptions
4.2.1 VCC
Digital supply voltage.
4.2.2 GND
Ground.
4.2.3 Port B (PB7..PB0)
Port B is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The
Port B output buffers have symmetrical drive characteristics with both high sink and source
capability. As inputs, Port B pins that are externally pulled low will source current if the pull-up
resistors are activated. The Port B pins are tri-stated when a reset condition becomes active,
even if the clock is not running.
Port B also serves the functions of various special features of the AT90PWM216/316 as listed
on page 67.
4.2.4 Port C (PC7..PC0)
Port C is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The
Port C output buffers have symmetrical drive characteristics with both high sink and source
capability. As inputs, Port C pins that are externally pulled low will source current if the pull-up
resistors are activated. The Port C pins are tri-stated when a reset condition becomes active,
even if the clock is not running.
Port C is not available on 24 pins package.
